Featuring a built-in water pump and bleed valve, it ensures consistent water circulation and efficient media dissolution using CO2 (not included). Ideal for stony coral tanks, it promotes healthy coral growth and stabilizes pH with minimal maintenance. ## Description ViaAqua® Acro-Cal™ Calcium Reactor AC 10 offers a simple and convenient solution for maintaining calcium and alkalinity in your reef tank, both being the backbone to a successful thriving reef environment. How does it works? CO2 is used to lower the pH in the reaction chamber. When the PH is lowered to 6.5-6.8 the circulating water and low pH begins to break down the media creating effluent water that is saturated with carbonates and calcium that continuously drip back to the aquarium. After the initial setup, the calcium reactor requires minimal maintenance. A calcium reactor is almost a necessity for tanks heavily stocked with stony coral, where calcium and alkalinity demands are high and will promote coral line algae growth. Acro-Cal™ Calcium Reactor provides a steady of calcium by using CO2 to dissolve media in the reactor and, thus, releasing calcium into your water. The effluent released also acts as a buffer to stabilize kH. Review: Exactly as described. Works great!! Easy instructions and set-up was simple.

Works great!! Easy instructions and set-up was simple. ### ⭐⭐⭐⭐⭐ Review *by A***R on 11 April 2017* good ### ⭐ Review *by C***A on 11 November 2018* It leaks from all connections. Will not function correctly. Fills up with gas, doesn't liberate gas correctly. Runs internal pump dry which breaks and melts with 3 days... Very fiddly if it does work, cannot be adjusted and just left. Dual input of gas and water - REALLY, REALLY BAD DESIGN.
